放射診斷設備之輻射安全與醫療曝露品保作業研究 (102年度)

According to the Article 17 of Ionizing Radiation Protection Act enacted since 2005, medical exposure quality assurance plan was drawn up based on the Standards for Medical Exposure Quality Assurance in order to improve the equipment quality as well as to keep the radiation dose reasonable low. Except for the radiological treatment equipment, quality control of mammography and computed tomography (CT) equipments have been included in the regulation since 2007 and 2011, respectively. The purpose of this project is to help understanding the equipment performance and current status of quality assurance programs of about 460 CT, 260 mammography systems and 50 fluoroscopy equipments based on both on-site measurements and questionnaires, which could served as references for the regulation for the Authority. Data of radiation dose for the radiological equipments and clinical dose distribution for the patients could also be obtained for references. Based on the dose data evaluated in the project, recommendations for further improve the quality both in equipment and technical aspects could also be made. Besides the on-site measurements and questionnaires described above, some research is also included in the project, such as evaluation of automatic tube current modulation in CT, optimization for pediatric CT protocols, analysis of breast and evaluation of factors affecting average glandular dose.
